Stated differently, dispatch controller 130 may determine that any elevator car of the plurality of elevator cars 210, 220 that is currently positioned beyond the first location may not be an optimal elevator car to answer the call request. In response to determining one or more of elevator cars 210, 220 are not located before the first location, dispatch controller 130 may be configured to disregard the particular elevator car 210, 220 from further consideration, at step 308.
  • first elevator car 210 is positioned between fourth floor 204D and third floor 204C and second elevator car 220 is positioned at fourth floor 204D such that dispatch controller 130 may determine that each elevator car 210, 220 is currently located before the first location.
  • dispatch controller 130 may be configured to determine an occupant capacity of each elevator car 210, 220 in response to determining elevator cars 210, 220 are positioned at a location in elevator shaft 202, 220 prior to the first location (e.g., second floor 204B).
  • dispatch controller 130 may be configured to determine a number of occupants 10 within each elevator car 210, 220 by retrieving active occupant data 142 from the respective counter device 125 located within each elevator car 210, 220.
  • counter device 125 may be configured to detect a total number of occupants 10 and/or objects 12 located within each elevator car 210, 220 (see FIG. 3 ).
  • dispatch controller 130 may consider one or more objects 12 detected by counter device 125 when determining the number of occupants 10 at step 312.
  • Each counter device 125 may transmit a signal to dispatch controller 130 via network 115 indicative of the active occupant data 142 for the respective elevator car 210, 220.
  • dispatch controller 130 may determine first elevator car 210 includes a single occupant 10 and second elevator car 220 includes two occupants 10.
  • dispatch controller 130 may be configured to determine a number of calls previously assigned to each elevator car 210, 220 (e.g., by dispatch controller 130) and that have a (pickup) location positioned between a current location of each elevator car 210, 220 and the first location. Stated differently, dispatch controller 130 may determine how many, if any, intermediate stops each elevator car 210, 220 is expected to perform between its current location and the first location (e.g., second floor 204B). It should be understood that the number of calls previously assigned to elevator cars 210, 220 is relative to when the call request at step 302 is received by dispatch controller 130.
  • dispatch controller 130 may be configured to disregard any prior calls assigned to elevator cars 210, 220 which have a (pickup) location after the first location when determining the number of calls at step 314.
  • first elevator car 210 may include a previously-assigned call at third floor 204C such that dispatch controller 130 may determine that first elevator car 210 includes one assigned call located between the current location of first elevator car 210 (e.g., between fourth floor 204D and third floor 204C) and the first location (e.g., second floor 204B).
  • second elevator car 220 may not include any previously-assigned calls such that dispatch controller 130 may determine that second elevator car 220 includes zero assigned calls located between the current location of second elevator car 220 (e.g., fourth floor 204D) and the first location (e.g., second floor 204B).
  • dispatch controller 130 may be configured to determine a number of prospective occupants 20 at the location of each call previously assigned to elevator car 210 (step 314). In some embodiments, dispatch controller 130 may determine that the location of each call previously assigned to elevator car 210 may include at least one prospective occupant 20. In this instance, at step 318, dispatch controller 130 may determine a total occupancy of each elevator car 210, 220 by computing an aggregate of the number of occupants 10 physically present within elevator cars 210, 220 (step 312) and the number of prospective occupants 20 located at each previously-assigned call (step 314).
  • dispatch controller 130 may determine first elevator car 210 includes a total occupancy of two, e.g., one occupant 10 within first elevator car 210 and at least one prospective occupant 20 at third floor 204C.

  • dispatch controller 130 may determine that the location of each call previously assigned to elevator car 210 may include a maximum number of prospective occupants 20 at step 316. In this instance, dispatch controller 130 may determine the maximum number of prospective occupants 20 at the location of each call previously assigned to elevator car 210 corresponds to the passive occupant data 144 stored on memory 136 for that particular location (e.g., third floor 204C). In the example, passive occupant data 144 may indicate an aggregate of two occupants 20 previously traveling to third floor 204C by at least one of the plurality of elevator cars 210, 220 at a point prior to receiving the call request at step 302. Accordingly, dispatch controller 130 may determine the call assigned to first elevator car 210 from third floor 204C may include two prospective occupants 20.
  • dispatch controller 130 may determine first elevator car 210 includes a total occupancy of three, e.g., one occupant 10 within first elevator car 210 and a maximum of two prospective occupants 20 at third floor 204C.
  • the passive occupant data 144 stored on memory 136 may be periodically updated by dispatch system 100 throughout continued use of the plurality of elevator cars 210, 220 in working environment 200. Accordingly, the passive occupant data 144 for each of the plurality of floors 204A-204B may be dynamic and continuously modified to track a current number of occupants 20 located at each floor 204A-204D. It should be understood that the current number of occupants 20 may increase and/or decrease based on the number of occupants 10 traveling to and from each floor 204A-204D via the plurality of elevator cars 210, 220, as detected by counter device 125.
  • dispatch controller 130 may be configured to determine an occupancy ratio of each of the plurality of elevator cars 210, 220 based on at least the total occupancy (step 318) and a maximum occupant capacity of each elevator car 210, 220.
  • a maximum occupant capacity of each elevator car 210, 220 may be communicated to dispatch controller 130 from counter device 125 via network 115.
  • dispatch controller 130 may store the maximum occupant capacity in memory 136 for each of the plurality of elevator cars 210, 220. It should be appreciated that a size and/or shape of the cabin of each of the plurality of elevator cars 210, 220 may be determinative of a maximum occupant capacity.
  • the plurality of elevator cars 210, 220 may include a substantially similar size and/or shape such that the maximum occupant capacity of first elevator car 210 and second elevator car 220 are relatively similar. In other examples, the plurality of elevator cars 210, 220 may include a varying sizes and/or shapes such that the maximum occupant capacity of first elevator car 210 and second elevator car 220 may differ relative to one another.
  • dispatch controller 130 may be configured to determine first elevator car 210 has an occupancy ratio of approximately 2:6 (e.g., approximately 33.33%).
  • dispatch controller 130 may be configured to determine first elevator car 210 has an occupancy ratio of approximately 3:6 (e.g., approximately 50%).
  • dispatch controller 130 may be further configured to determine second elevator car 220 has an occupancy ratio of approximately 2:6 (e.g., approximately 33.33%).
  • dispatch controller 130 may be configured to determine at least one of the plurality of elevator cars 210, 220 having a maximum available occupant capacity to assign the call request to. Dispatch controller 130 may compare the occupancy ratios of each of the plurality of elevator cars 210, 220 to determine the at least one elevator car 210, 220 having the maximum available occupant capacity. In the example, with first elevator car 210 and second elevator 220 each having an occupancy ratio of approximately 50%, dispatch controller 130 may be configured to compare the motion data 140 to determine one or more motion parameters of the plurality of elevator cars 210, 220 (e.g., a current location, a travel speed, a status, etc.).
  • Dispatch controller 130 may compare the motion data 140 to determine which of the plurality of elevator cars 210, 220 to assign to the call request to when elevator cars 210, 220 have a similar maximum available occupant capacity. For example, dispatch controller 130 may assign the call request to first elevator car 210 based on a distance between first elevator car 210 and the first location (e.g., second floor 204C) being less than a distance between second elevator car 220 and the first location. By way of further example, with first elevator car 210 having a previously-assigned call and second elevator car 220 not having a previously-assigned call, dispatch controller 130 may determine to assign the call request to second elevator car 220 based on a travel speed of second elevator car 220 being greater than first elevator car 210.
  • dispatch controller 130 may be configured to assign the call request to second elevator car 220 having the greater maximum available occupant capacity. In this instance, second elevator car 220 may be assigned the call request at step 324. In some embodiments, dispatch controller 130 may compare the motion data 140 of the plurality of elevator cars 210, 220 when the occupancy ratio of the plurality of elevator cars 210, 220 vary relative to one another. In this instance, dispatch controller 130 may be configured to assign the call request to at least one elevator car 210, 220 despite another one of the plurality of elevator cars 210, 220 having the greater maximum available occupant capacity.
  • dispatch controller 130 may be configured to communicate with call device 100 to transmit a message to the prospective occupant 20 at the first location (e.g., second floor 204B). For example, dispatch controller 130 may communicate an identification of the at least one of the plurality of elevator cars 210, 220 assigned to answer the call request. In other embodiments, dispatch controller 130 may identify the at least one of the plurality of elevator shafts 202, 212 from which the elevator car 210, 220 may arrive from.
  • the message may be transmitted via call device 110 in various suitable formats, including, for example, via a display (e.g., a written form, a graphic form, etc.), a speaker (e.g., an audible form), and more.
